Despite widespread media attention, 75 percent of users remain unaware of Heartbleed and its potential threat to user security, according to a survey of 268,000 conducted by security company AVAST. Furthermore, 41 percent of respondents aware of Heartbleed didn't want to change passwords, saying they didn't believe they were affected.

At the very least, security experts recommend changing passwords now, with most major websites already fixing the vulnerability. Security companies continually urge users have multiple passwords, and recommend utilizing a password manager instead of trying to memorize - or write passwords down on paper - to stay secure.

Heartbleed garnered significant attention among casual users, with local newspapers and TV stations covering the vulnerability - but that still didn't ultimately change how users reacted. Earlier this month, it was estimated at least 300,000 servers were still vulnerable to Heartbleed, while the Department of Homeland Security even stepped up to offer security tips.
